Presentation Outline
� Existing gas & electricity interconnections
� Proposed Gas Interconnectors
� Proposed Electricity Grid Interconnections
� Benefits arising from the operation of interconnectors
� Interconnectors as key elements of long term energy strategy
-
Introductory Observations
� Energy security is key objective for all countries
in SE Europe
� Need to secure smooth flow of fuel supplies
within each country and between countries in within each country and between countries in
the region
� Interconnectors to be seen as effective energy
bridges
� Interconnectors can secure operation of
alternative and secondary energy routes,
therefore enhancing energy security
-
Existing Gas & Electricity Interconnectors
� In view of the size of gas volumes transported each
year in the region, (85 BCM’s) the number and size of
interconnectors is limited
� As plans are currently in progress to use SE Europe as
a transit area for large inter-regional gas pipelines the a transit area for large inter-regional gas pipelines the
need for interconnectors is paramount
� Electricity grid connections between countries in SE
Europe are more extensive than gas, thus contributing
to much bigger energy flows
� Interconnectors both gas and electricity, are essential
for the operation of integrated electricity & gas markets
as envisaged by the “Energy Community”

Major Proposed Inter Regional Gas
Pipelines
� Nabucco (30-32 BCM’s)
� South Stream (63.0 BCM’s)� South Stream (63.0 BCM’s)
� ITGI (10-12 BCM’s)
� TAP (10-20 BCM’s)
-
Proposed Gas Interconnectors – Group I (East Balkans)
� Greece-Bulgaria-Romania-Hungary Interconnectors and
Greek LNG Terminals to comprise:
� Komotini-Stara Zagora (170 kms) gas interconnector
(known as IGB)
� Kavala LNG terminal� Kavala LNG terminal
� Bulgaria-Romania interconnector known as IBR, (15 kms)
crossing the Danube
� Romania-Hungary Interconnector (109 kms) known as IRH
(to link Arad in Romania to Szeged in Hungary)
All three interconnectors to be built with reverse flow
capacity
-
Proposed Gas Interconnectors – Group II (West
Balkans)
� The Croatian-Hungarian Gas Interconnector and the
Krk/Adria LNG Project
� Crotia-Hungary, known as ICH
� Krk LNG terminal (10.0 BCM/y capacity)
� The objective of ICH is to increase Hungarian import diversification away from Russiadiversification away from Russia
� Bulgarian-Serbian Gas Interconnector
(80-100 kms, with 2.0 BCM/y capacity)
� Western Balkan Gas Ring Project� Entails the construction of several small to medium capacity n.gas
interconnectors between the whole region of former Yugoslavia (No
progress has been reported over the last 2 years)

Conclusions
� Interconnectors are seen as key elements in the
region’s long term energy strategy
� Interconnectors, both electricity and gas, are
cost effective because of their relatively small cost effective because of their relatively small
size, therefore low capital cost and speedy
construction
� Interconnectors can be easily planned as their
operation does not depend on new gas or
electricity supplies
-
Conclusions
� They further contribute towards:
� import diversification
� increased security of supply
� improvement of system operation by providing
cushion supplies cushion supplies
� improvement of storage capacity (in the case of gas)
� greater system flexibility
� improvement of overall energy flows
� optimized economic system operation
� Governments must give priority to electricity & gas interconnections over large scale intercontinental projects
